Car isn't starting all the time. Has a New Fuel filter and fuel pump is putting out enough pressure. has a new battery. if when it soesn't start you spray ether into the air cleaner it will run and stay running. then about 4 or 5 times later and sometimes the next time it won't start. The starter turn over great. When we checked to see if any codes would come up it was empty. the car has 63,000 miles.

    Our CTS won't consistently start. It's warm here and it doesn't seem to start when the car is warm toward the end of the day. The engine cranks over fine. I've been able to get it to start by continuing to try, but my wife and a tow truck driver have not. I've replaced the fuel filter with no luck. The mechanic found no codes in the computer and came up empty handed.

That's what was finally found by our Cadillac dealer as well. They charged us too much, though.

Hey Guys! Had the same annoying problem. Cadillac dealer could find nothing wrong with it. Gave me a new battery. Took it to PepBoys and it died for them and immediately they found that it was the Crank Positon Sensor!! Part was $70 + labor. GOOD as NEW!!!!

I have a cadillac cts 2008, when i fill the tank with gas and open the key the engine does not star, i have to do it one more time. what is causing this problem?


When you open the gas cap, you relieve the pressure in the fuel system. Once you replace the cap, this pressure must be reestablished. All vehicles have a fuel system "prime" function that causes the fuel pump to run for about 3-5 seconds after turning the key to bring fuel pressure to the fuel rail. It sounds as though your system isn't getting enough pressure on the first prime, so you must cycle the key twice to get full pressure. It could be a sign of the fuel pump starting to fail.

My 2003 cadillac want start but it sounds like it wants to what's the problem?


The problem is fuel related. Bad fuel pump, bad fuel pump relay or a leaking injector causing fuel pressure to bleed off when turned off. When starting the car up for the first time have somebody turned the key just to the one position while you listen to the fuel tank. you should be able to hear the fuel pump kicking on for a few seconds.

Sounds like a possible fuel filter. Bigger question - when was last tune up? With the different grades of fuel these days and with temps fluctuating a fuel filter would be my first thing to change.
